The font of the font library displayed on the ink screen is very light. Is it the reason for the font library display function

Ink screen lilygo-epd47.

I use the same font library. The following two different driver libraries display the effect of weather respectively. I find that the font displayed when using epdiy library is light:

Because the ink screen is 16 colors, I suspect you don't use all black when displaying the font.

Please check, thank you!
